Control Registers
This microcontroller uses the memory-mapped-I/O method and allocates the peripheral circuit registers to the
internal I/O space between addresses x'20000000 and x'3FFFFFFF.
The registers listed below are described in this section. For details on other control registers, refer to the respective
sections that explain the various internal peripheral functions.
